valtimo-backend-libraries: Incorrect Authorization

Published Updated By the CyberSecBulletin desk

CVE-2025-48881 is a high-severity incorrect authorization vulnerability in valtimo-backend-libraries from Valtimo-platform, with a CVSS 3.1 base score of 8.3 out of 10. It can be exploited remotely over the network by an attacker with a low-privileged account, without any action from a user. Affected valtimo-backend-libraries versions: >= 11.0.0.RELEASE, <= 11.3.3.RELEASE; >= 12.0.0.RELEASE, < 12.13.0.RELEASE. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.35% chance of exploitation within 30 days, which is low compared with other CVEs.

Official description

Valtimo is a platform for Business Process Automation. In versions starting from 11.0.0.RELEASE to 11.3.3.RELEASE and 12.0.0.RELEASE to 12.12.0.RELEASE, all objects for which an object-management configuration exists can be listed, viewed, edited, created or deleted by unauthorised users. If object-urls are exposed via other channels, the contents of these objects can be viewed independent of object-management configurations. This issue has been patched in version 12.13.0.RELEASE. A workaround for this issue involves overriding the endpoint security as defined in ObjectenApiHttpSecurityConfigurer and ObjectManagementHttpSecurityConfigurer. Depending on the implementation, this could result in loss of functionality.

The underlying weakness: Incorrect Authorization

The product performs an authorization check when an actor attempts to access a resource or perform an action, but it does not correctly perform the check.

How developers prevent this class of flaw

  • Divide the product into anonymous, normal, privileged, and administrative areas. Reduce the attack surface by carefully mapping roles with data and functionality. Use role-based access control (RBAC) to enforce the roles at the appropriate boundaries. Note that this approach may not protect against horizontal authorization, i.e., it will not protect a user from attacking others with the same role.
  • Ensure that access control checks are performed related to the business logic. These checks may be different than the access control checks that are applied to more generic resources such as files, connections, processes, memory, and database records. For example, a database may restrict access for medical records to a specific database user, but each record might only be intended to be accessible to the patient and the patient's doctor.
  • Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid. For example, consider using authorization frameworks such as the JAAS Authorization Framework and the OWASP ESAPI Access Control feature.
